NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 14726-1:1999 ‘Ships and marine technology— Identification colours for the content of piping systems — Part 1 : Main colours and media’ issuedby the International Organization for Standardization (ISO) was adopted by the Bureau of IndianStandards on the recommendations of the Shipbuilding Sectional Committee and approval of theTransport Engineering Division Council.

However Shipbuilding Sectional Committee will decide in future for adoption of ISO 14726-2:1999‘Ships and marine technology — Identification colours for the content of piping systems — Part 2 :Additional colours for media and/or functions’.

The text of the ISO Standard has been approved as suitable for publication as an Indian Standardwithout deviations. Certain conventions are, however, not identical to those used in Indian Standards.Attention is particularly drawn to the following:

a) Whereuer the words ‘International Standard’ appear referring to this standard, they should beread as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker in the International Standards, while in IndianStandards, the current practice is to use a point (.) as the decimal marker.

The Technical Committee responsible for the preparation of this standard has reviewed the provisionsof the following International Electrotechnical Commission (l EC) Standard and Cl E publication havedecided that the same is acceptable for use in conjunction with these standards:

SHIPS AND MARINE TECHNOLOGY —IDENTIFICATION COLOURS FOR THE CONTENT OF

PIPING SYSTEMSPART 1 MAIN COLOURS AND MEDIA

1 Scope

This part of ISO 14726 specifies the main colours for identifying the content of piping systems in accordance withthe conveyed media on board ships and marine structures.

This part of ISO 14726 does not apply to piping systems for medical gases, industrial gases and cargo.

These colours may also be used for piping systems on drawings and diagrams.

NOTE Additional colours will be given in ISO 14726-2: Ships and marine technology — Identification colours for thecontent of piping systems — fart 2: Additional colours for media and/or functions.

2 Normative references

The following normative documents contain provisions which, through reference in this text, constitute provisions ofthis part of ISO 14726. For dated references, subsequent amendments to, or revisions of, such publications do notapply. However, parties to agreements based on this part of ISO 14726 are encouraged to investigate the possibilityof applying the most recent editions of the normative documents indicated below. For undated references, the latestedition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently validInternational Standards.

3 Term and definition

For the purposes of this part of ISO 14726, the following term and definition applies.

3.1main colowcolour used to indicate a group of similar media

NOTE More detailed marking is effected by applying a deviating additional colour. The deviating additional colours will begiven in ISO 14726-2 w’hich is under preparation.

5 Design

5.1 General

The main colours maybe

— applied to the pipeline as an adhesive tape or sign;

— painted onto the pipeline in transverse stripes;

— painted onto the pipeline on the total length. ,

The markings shall be so positioned that the colour stripes (tapes) are in a direction perpendicular to the axis of thepipe.

Pipelines shall be marked as follows:

— once in each room, at least;

— at each penetration point in bulkheads, walls and decks;

— close to each valve;

— within a distance of 3 m to 5 m of the length of the pipeline, whereby the local conditions may require a morefrequent marking due to pipe bends or the close proximity of pipes for different services.

Paints and adhesives of self-adhesive identification labels or coloured tapes shall neither attack nor damage thesurface of the pipe components that are to be marked.

5.2 Marking of pipes with tapes

Pipes of up to 200 mm outer diameter:

— the tapes comprise the entire circumference of the pipes and are adhered at their ends by overtaking

Pipes of more than 200 mm outer diameter:

— the tapes comprise about half the circumference of the pipes.

Pipes in bundles:

— shall be individually marked.

if the marking is not possible over the entire circumference, an abbreviation of the marking is admissible.

A common marking of several pipes with the same content or function is only admissible on collars.

6 Additional markings

6.1 Additional colours

Additional colour markings may be added adjacent to a main colour marking on a pipe, when necessary, to

distinguish between pipes marked with the same main colour listed in Table 2, but carrying different types ofmedium. (For example, a pipe carrying diesel fuel oil and a pipe carrying heavy fuel oil.)

The area (or width) of additional colours shall be less than the area (or width) of main colours so that it is clearlyapparent what are the main colours and what are additional colours.

IS 15445 (Part 1):2004ISO 14726-1 :1999

6.2 Supplementary indications

Arrows to indicate the direction of flow in a pipe are recommended. Pipes with flow in opposite directions at differenttimes may be marked with arrows pointing in opposite directions.

Additional marking by text is also recommended to signify unambiguously the content and/or function of the pipe.When additional markings by text are used, consideration should be given to the use of a language understood bythe crew members whose responsibilities include being able to identify pipes and piping systems.
